RocKlNG-CHAIR.

SPECIFICATION forming part of Letters Patent No. 279,879, dated Junev19, 183. Application filed February 23, 1883. (No model.)

To all whom it may concern:

Beit known that I, CHARLEs NIEMILLER, a citizen of the United States,residing at Cincinnati, county of Hamilton, State of Ohio, have inventedcertain new and useful Improvements in Rocking-Chairs, of which thefollowing is a specication.

My'invention relates to that class of rockingchairs in which the rockingmember is retained in place and permitted to vibrate upon a stationaryplatform by a retaining-spring which connects the two parts. Its objectis to secure an easy rocking motion, to prevent the rocker sliding' uponits base, and to insure the return of the rocker to a properposition,when at rest, without'weights, which are now required under thefront cross-rail in this class of chairs to counterbalancc the back.

With these objects in view my invention consists in certain details ofconstruction and combination of parts, as will be hereinafter described,and pointed out in the claims.

The accompanying drawing is a perspective View of a chair-frame providedwith my improvements.'

A is the stationary platform,'and B the rocking member.l These areconstructed in the usual manner, may be of any approved design orpattern, and need not be particularly described here.

C is a metal bar passing transversely be.- tween the rockers. Each endof the bar is bent up at a right angle, and secured, respectively, tothe inside of the rockers by two screws.

D is a steel spring, .centrally secured to the crosssbrace of thelplatform A by two bolts, a

a, which also pass through a curved metal ,i piece, E, which is alsofirmly secured upon top of the spring by the bolts. The ends of spring Dare formed into the shape of a letter S. The

ends beyond the curves are securely riveted to the cross-bar C.

The retaining device, consisting of the spring D and bar C, is intendedto be manufactured and sold separately, and when secured together isready for attachment to any chair of this class, and, if desired, thebar C may be left straight, so that the ends may be bent up by the userto suit any width of chair.

1After the chair is upholstered and finished the spring is secured uponthe cross-brace of the platform. The rocking frame is placed upon theplatform and held to the proper pothe crossbar C and spring D, the saidcross- 1- bar being rigidly secured between the rockers, and the springD being secured centrally to the platform, and its ends bent upward andsecured to the cross-bar C.

2. As a new article of manufacture, the springconnecting device forrocking-chairs of the character described, consisting ofthe bar C andspring D, the ends of the springs being S- shaped and connected to thebar near the ends thereof. i Y
